This invention relates to: a machine for labeling toilet paper rollsafter the latter has been cut into strips of the required widths andwound upon a suitable arbor or mandrel in co-axial relation end to end.7

That is, the paper is usually delivered from the paper-making machine inrelatively wide sheets and duringsuch delivery is cut into strips of thedesiredflength for the rolls and perforated at regular intervals,immediately following which the perforated strips of predeterminedlengths are wound upon the arbor thereby forming a multiplicity ofcoaXial rolls upon each arbor or mandrel.

The main object of the presentinvention is to provide simple andeificientmeans for automatically and expeditiously labeling the rolls assupplied to the machine upon the n mandrel. In other words I have soughtto take the mandrels with the multiplicity of rolls thereon directlyfrom the paper making machine and pass them through the labeling machinein such manner that all of the rolls ,5 on each mandrel will besimultaneously labeled.

One of the specific; objects isto provide a power driven mandrel carrierwith a pluralityof bearings for the mandrels arranged at spacedintervals throughout its length so that as soon as the rolls on' onemandrel have been labeled the bearings for another. mandrel with theunlabeled rolls thereon will be in position to receive that mandrelforre-. peating the labeling operation upon its rolls.

Another specific object is to provide means actuated by the bearingsafter the rolls thereon have been-labeled for automatically stopping themachine to permit unloading of the labeled rolls and reloading of theunlabeled rolls from and upon the conveyor.

Another specific object is to provide means for automatically applyingadhesive substance to the opposite ends of each label withthe mandrelswith therolls thereon along the rolled along and upon said label so thatthe out interrupting the continued movement of wrap the label around therolls as they are adhesive on the other end of the label willbe broughtinto overlapping. contact with the first named end of said label forsealing the same and thus complete the labeling operation for the rollson each mandrel without interrupting the operation of the machine.

rlr furtherobject is to provide means whereby the label holder will beintermittingly and automatically fed toward the path of movement of theloaded mandre'lsadistance corresponding approximately to the thicknessof the label immediately followingeach labeling operation.

another object is to provide means for adjusting certain parts of themachine for labeling rolls of different diameter. I

Other objects and uses relating to specific parts of the machine will bebrought out in the following description. In the drawings: i

M az'n support/{mg frame I As illustrated the main supporting frame issubstantially rectangular and comprises a pair of slmllarlongitudinallyextending upright sections 1 arranged in transverselyspaced parallel relation and connected near their ends by transverse tierods 2 which are surrounded by tubular spacing sleeves 3 abuttingagainst the inner faces of'the sections 1 to hold the latter in spacedparallel relation as shown more clear ly in Figures 1 to 6 inclusive andFigure with bosses 3 adapted to enter the adjacent ends of the spacingsleeves -3- to hold the latter against lateral displacement as shownmore clearly in Figure 6.

Two of these tie rods 2 and their spacing sleeves 3 are located near thelower corners of the frame sections 1- while the other tie rod 2 and itsspacing sleeve .3 is located near the upper front corner of the'framesections as shown more clearly in Figures 2, 3, 4 and 6.

A brace bar 2- extends across the intervening space betweenthe rear endsof the frame sections 1 and'is bolted or otherwise secured to saidsections as shown more clearly in Figure 6 and serves to receive andsupport a pair of brackets 1- which are bolted or otherwise secured tothe brace .bar 2 to extend upwardly therefrom for receiving andsupporting a horizontal delivery table or shelf5- as shown more clearlyinFigures 1, 2 and 5. V

" This delivery table or shelf 5 is arranged atthe rear end of themachine to '7- for each guide plate being arranged in longitudinallyspaced relation for a purpose hereinafter described.

These guide plates -6-- extend practically the entire length of theframe sections -1 in af'plane some distance above the upper faces ofsaidsections and are provided in their inner sides with lengthwisegrooves 6- extending from end to end thereof for receiving and guidingthe mandrel hearings on the conveyor presently described.

Mandrel conveyor mechanism A rotary power-driven cross shaft -8- isjournaled in suitable bearings -9- on the rear ends of the guide plates6 as shown more clearly in Figure 5 to extend transversely beneath thedelivery table 5 and is provided near the bearings '9- with a pair ofsprocket wheels 10 for receiving and supporting the adjacent portions ofa pair of link-belts -11.

These belts extend forwardly along corresponding sides of the machineand are mounted at their forward ends upon and around upper and lowerpairs of sprocket groove -6'- of the guide plates --6- so that theintermediate portion of the link belt 11- may ride along and upon saidlower lower wall as shown more clearly in Figure 3 while the lower sideof the chains sag more or less between the lower peripheral portions ofthe sprocket wheels -8- and lower set of sprocket wheels 12-.

It is now clear that the upper sides of the link-belts travel in ahorizontal plane along and upon the underlying wall or flange of theguide; plates '6-.f'or moving the man drels carrying the paper rollsalong the same plane in a mannerpresently described;

The upper sides of the link belts extend horizontally practically theentire length of the machine, one of said belts beingprovided with aplurality of, in this instance three, bearing blocks -l5 secured theretoin uniformly spaced relation longitudinally and adapted to slide alongthe corresponding guide plate --6- as the conveyor is moved in thedirection indicatedgby arrows in Figures 3 and 4, P

Journaled in each of theblocks ;15 is a rotary member -16 having asquare socket 17open at its inner end for receiving'the adjacent squareend of the roll supporting mandrel presently described. See Figure 19.

The other link belt is provided with acorresponding number of bearingblocks -15- in transverse alignment with the blocks 15 and adapted toslide within and upon the adjacentguide plate 6-, each of'the blocks 15being provided with a socket 17 open at the topto receive the adjacentends o-fthe mandrels and to anew the latter to turn in their respectiveblocksduring the labeling operation, v

It isnow evident that each bearing block -1 5- and its companion block-15 is .adapted to receive and support one of the loaded mandrels duringthe labeling operation and that'the object of the open sided sockets 17is to facilitate the placing and removing of the loading mandrels uponand from the blocks-'l5 and 15%j just preceding and succeeding thelabeling operation. Uomieyor driving means d An electric motor M- ismounted upon a bracket '18 on one of the upright sections -l with itsarmature shaft m extending lengthwise thereof and provided with a worm19--'mesh1ng with a wormgear 20 which, together with the worm 19, ismounted within a suitable gear case i18' on the adjacent upright section1 of the mainsupporting frame as shown more clearly in Figure 23.

That is, the gear case l8"-, is bolted or otherwise secured to theadjacent upright portion of the near section 1 of the main supportingframe'and-is provided with suitt able bearings for the motor shaft 7wand the supporting shaft as -2l for the gear A'pulley -22 is secured tothe inner end of the gear shaft 21'- and is connected by a belt 23 to arelatively larger pulley 524- on the corresponding end of the rear crossshaft 8- carrying. the conveyor sprockets 11 as shown more clearly inFigures 4, 5 and 22, the belt being tightened upon its 7 supportingpulleys -2'2 and.

means of a belt-tightener 25,, as shown in Figures 4, 5 and22.

I :Itwillibe noted that the driving connections between the motor -M andconveyor shaft '-8 are arranged to drive the conveyor belts atrelatively low rate of speed for effecting a corresponding slowmovementof the loaded mandrels along and upon the guide plates +6 duringthe labeling operations, it being understood that three of theselabeling operations occur during each cycle of- I upon a mandrel b--having one end square and adapted to be, inserted into the correspondlngsocket -17 of one of the bearing members -l5 and its other end placed inthe socket 17-- of thecompanion bearing block 15. s V

This loaded mandrel with the unlabeled rolls thereon is placed in thecorresponding set of bearing members 15'and 15'-' while the conveyor isat rest with one set of bearing blocks at the front end of the machineand the nearest preceding set of bearing blocks at the rear of themachine, the third set being then on the underlying side of the chainbelts from which the mandrel carrying the previously labeled rolls hasbeen removed to permit said hearings to receive another loaded mandrelwhen brought to the front end of the machine by further movement of theconveyor.

A self-closing electric switch s-, Figure 21, is connected in the motorcircuit and is normally closed to cause the operation of-the -motor'andconveyor mechanism for feeding the loaded mandrels from front to rear ofthe machine during which the labels are automatically applied to therolls in a manner. hereinafter'described but immediately following thelabeling operation for each loaded mandrel the switchs will beautomatically opened by the engagement of one of the switch blocks as--15 with a switch-operating member as 26, shown diagrammatically inFigure 21 and in full in Figure 4.

That the member -26- is pivotally mounted upon a switch box -S- on therear end of one of the guide plates 6 as shown in Figure 4 to normallyproject into the path of movement of the blocks 15 on'the correspondingside of the machine to be engaged by each block for breaking the motorcircuit and thereby stopping the motor and conveyor driven therebyimmediately following the labeling operation. A switch box S is mountedin the top of'the front lefthand side of the frame of the machine asshown in Figures 1 and 2, and contains a self-opening starter switch s'which is connected in the motor circuit (Figure 21) and is adapted to'beclosed by a push button -S (Figures 1 and 2) for starting the motorafter it has .been automatically stopped by the opening of the switch26. That is, while the conveyor is at rest with one of the mandrelscarrying its load of labeled rolls at the rear end of the machine,another mandrel with its unlabeled rolls is placed in the bearings '15-and -15- at the front of the machine. The switch S is then temporarilyclosed by the depression of the push button S- to start the'motor andconveyor until the switch S- is al-' lowed to close by the shifting ofthe adjacent member -15- at which time the switch -S may be released andallowed to open with the assurance that the motor and conveyor willcontinue to feed thes'econd named mandrel and its rolls from front torear of the machine for labeling the rolls or until the switch S isagain opened by the corre sponding member 15- of the conveyor,

this operation being repeated for each loaded mandrel. H

Supplemental 7 frame Each of the upright framesections 1 is providedintermediate its ends with a pair of similar upright guide posts 27bolted or otherwise secured thereto in longitudinally spaced relation toproject inwardly therefrom as shown more clearly in Figures 3, 4 and 6and having their inner sides provided with vertical T-shaped slots -28for receiving and guiding a vertically movable supplemental frame uponwhich the parts of the label holders are guided in a manner presentlydescribed.

qThis supplemental frame comprises a pair of similar upright platesections. 29 extending lengthwise of the machine in transinner faces ofthe upright guide bars27- as shown more clearly in Figures 2', 5 and 6,

each plate section 29 being provided with. a pair of outwardlyprojecting T-shaped ribs s5-30-. complementary to and engaged in thecorresponding guide grooves 28 for holding the'plates, in spacedparallel relation and guiding them in their vertical movement. Suitablemeans is provided for raising and 3 lowering the side plates -29 of thesupplemental frame with the various mechanisms thereon to compensate forvarying diameters of the paper rolls to be labeled and for this purposethe plates 29 are provided with 91; vertical threaded apertures 31adapted to vers'ely spaced parallel relation adjacent the ous verticalmovement of the carrier frame be engaged by right and lefthand screwshafts '32 and 32 respectively having their lower ends journaled insuitable brackets 33 on the lower lengthwise bars of the main supportingframe 1 as shown more clearly in Figure '13.

The lower ends 'of these upright screw shafts 32 and 32' are providedwith beveled gears 3al meshing with companion gears -.35 on a crossshaft 36 which i is journaled in suitable bearings in the brackets 33and is provided at one end with a hand wheel 37 bywhich it may be turnedfor transmitting rotary motion to both of the upright shafts through themedium of the companion gears. See Figure 13.

Label carrier The portions of the upright side plates 29- of thesupplemental frame between the $5 cross shaft 36 and guide bars 27- areprovided in their inner faces with vertical T-shaped slots -38 forreceiving complementary vertical ribs 39 on the pendant C extensions 40of a horizontally extending 1' U-shaped frame 4l which forms a part ofthe label carrier and is arranged with its cross bar facing rearwardlyand its opposite arms extending forwardly as shown more 3 clearly inFigure 5, said forwardly extending arms being connected by additionalcross barsr -4=2 in longitudinally spaced relation from each other andfrom the rear cross bar. See Figs. 6 and 25.

The upper faces of the cross bars of the U-shaped frame 4:1 are disposedin substantially the same horizontal plane for receiving and supportingamultiplicity of label supporting tables 42 corresponding to the numberof, rolls to be labeled on each loaded mandrel. See Figures 2, 5, 7 and8.

The pendantarms i0 are arranged in transversely spaced parallel relationnear the inner faces of the opposite side plates 29- as shown in Figure6 and are provided with vertical threaded apertures -43 adapted to beengaged by separate screw shafts 44 and 44 having right and lefthandthreads respectively for effecting simultanei1 in one and thesamedirection independently of the side plates 29 for bringing the uppermostlabels into position to be engaged by the rolls aonthe mandrel b.

The lower ends of the shafts i4' and 4& are journaled in suitablebrackets 45 which are bolted or otherwise secured to the lowerlengthwise bars of the main sup porting frame which is shown moreclearly in Figures 4 and 23 and are provided with beveled gears 46meshing with companion gears 46.- on an underlying cross shaft 47, thelatter being also journaled in suitable bearings in the brackets -4c5 asshown more clearly in Figure 25.

One end of the shaft -47- is provided with a hand wheel 48 by whichjitmay be rotated to effect a corresponding rotation of the screw shafts 41 and 4-4 and'resultant vertical movement of the label supportingframe4l along the upright guide grooves 38 in the side plates 29' foradjusting the label support with the labels thereon toward and from thepath of move ment of the mandrels carrying the rolls to be labeled, thisadjustment: being independent of the vertical adjustment of the sideplates 29' along the guide bars 27 for feed ing the labels to the rollsas they are successively wrapped around the rolls. I

An additional U-shaped member 4:1 similar to the member 41 is mountedupon the opposite arms of said member ll for lengthwise sliding movementand for this purpose the opposite arms of the member i1 are providedwith lengthwise slots 4;1 for receiving guide bolts or studs 41 on theopposite adjacent arms of the member 41 the object of which is to permitthe label supporting table to be lengthened or shortened according tothe lengths of the labels. See Figure 2.

The bars 41 and 4t1 extend continuously transversely of the machinebetween the side plates 29 for receiving and supporting a multiplicityof label supporting tables l2' corresponding to the number of rollscarried by each mandrel, each table being composed of relatively thinsheet metal sections 4-2 and .4-2-, one set of which, as 42"-, issecured to the U- shaped member 1l while the other set as -42" issecured to the U-shaped member 4l', which, together with the plates 42-,are adjustable endwise to vary the length of the table according to thelength of the labels supported thereon as may be required for rolls ofdifferent diameters. See Figures 1, 2 and 5.

The label supporting tables or tablets 42 are of about the width of theindividual stacks of labels which they are adapted to support and are ofslightly less width than the rolls upon whichthelabels are adapted to bewound so that the meeting edges of the several tablets are slightlyseparated to receive between them guide membersfor holding-the labelsagainst lateral displacement during the rolling operation of themandrelswith the rolls thereon along and upon the uppermost label in a mannerhereinafter described.

The portions of the side plates 29 in front of the vertical shafts 32and 32 are provided on their inner faces with lengthwise guide grooves49 of T-shaped cross section for receiving complementary portions of apair of longitudinally adjustable slide plates 50 having lengthwisethreaded openings 51- for receiving separate screw shafts 52 as shownmore clearly in Figures 6, 14 and 15.

The front ends of these shafts are journaled in suitable bearings 53 onthe adjacent ends of the side plates -29 and are provided with handwheels 54. by which they may be turned for adjusting the slides -50along the guideways 49 for a purpose presently described. See Figures 5,6, 14 and 15.

Suitable means is provided for engaging the opposite ends of the labelsto assist in guiding them in their vertical movement with thecorresponding movement of the tables -4-2. and also for holding saidlabels against endwise displacement during the labeling operations andfor this'purpose a pair of vertically disposed abutment plates 55'- and55- are mounted respectively upon the vertically movable side plates 29and the horizontally movable slides 50 at opposite ends of the labelsupporting tables i2 as shown more clearly in'Figure 2.

These abutments extend some distance above and below the horizontalplane of the tables f12 and also laterally beyond said tables inparallel relation a distance apart and are supported endwise independentof the tables sothat the latter with or without the labels thereon arefree to move vertically between the end abutments.

Tlhe opposite ends of the rear end abutment 55 are secured to the innerfaces of the upright side plates 29 by angle irons 56-, Figure 5, whilethe opposite ends of the front abutment 55 are secured by similar angleirons '56 to the inner faces of the adjacent slides 50 to movehorizontally therewith, it being understood. that both of the endabutments may be adjusted vertically with the side plates 29 as thelatter are adjusted through the medium of the screw shafts 82 previouslydescribed. SeeFigures 14 and 15.

lVhile the slides 50 are adjusted horizontally through the'mediumof thescrew shafts 52, the U-shaped bar 4l carrying the table sections 42 willbe ad justed by hand, these adjustments being made necessary toaccommodate labels of different lengths.

The side plates 29 are connected near their front ends by a tie rod 29'having its opposite ends seated in suitable sockets in the side platesand held against turning movement by pins -29 as clearly in Figure 6. V

A plurality of upright guide fingers 57' are secured at their lower endsto the tie rod 29 to extend upwardly therefrom through the spacesbetween andabove the label supporting tablets 42-, said tie-rod beingprovided with similar guide fingers exshown more 9. engaged in threadedapertures in the memthrough the spaces between and along the outer edgesof the outermost label supporting plates 4-2" as shown more clearly inFigures 1,2- and 5/ Suitable means is provided for holding theintermediate portions of the end abutments 5 5- and 55 and tie rods 29'and 29- against lateral vibratory movement, said means consisting inthis instance ofa pair of upright bars -59- and 59 clamped to the loweropposite-end spacing sleeves 3 substantially midway between the oppositeupright side sections 1,Figure 2, for receiving a pair of inverted l..-'shaped members 60 and 60, the upright portion of the member 60 beingprovided with vertical slots 61 for receiving clamping bolts 62- whichare engaged in threaded apertures in the upright members 59, Figure 2.

The horizontal upper portion of the member -60 is clamped to theintermediate portion of the tie rod 29 to hold the latter againstvibration, said horizontal portion being provided with an upwardlyprojecting extension 63 which is bolted or otherwise secured to the rearface of the adjacent end abutment 55 as shown in FigureQ, therebyholding the intermediate portion of the abutment against vibration.

The object of the slot and bolt connections between the upright portionof the members 59- and 60- is to permit vertical adjustment of the uppermember 60- with the side plates -29 to which the tie rod 29 is secured.

The upright portion of the L-shaped member 60 is provided with slots-6&- for receiving clamping bolts -6t'- which are her 59 to permitvertical adjustment of the members 60 with the side plates 29- whichcarry the slides 50-.

The upper horizontalportion of the member -60 is provided with a slot 65for receiving clamping bolts 65 which are engaged in threaded aperturesin the lower end of an upwardly projecting bracket 66 to which the frontend abutment 55' is bolted or otherwise secured, the member 66 havingits rear end clamped to the adjacent tie rod 29- for holding the latteragainst vibration and also performing a similar function for theintermediate portion'of the abutment 55 See Figure 2.

- Owing to the fact that the front end abutment 55- 'is secured to theslides 50 and that the member 66- is secured to the intermediate portionof the front end abutment and to the tie rod 29" said member 66- becomesindirectly a part of the slides 50 in that it is adapted to be adj ustedhorizontally with said slide by reason of the slot and bolt connections-65 and 65- between the members 60- and 66, see Figure 2.

The opposite lengthwise guide bars -6 for the mandrel bearings 15 and15' on the link belts 11 are provided with downwardly projectinglengthwise extensions 67 and 67' supported'by the legs -7- to formlengthwise guides for a pair of similar brackets 68 and 68 which areadjustable along and upon their respective connections 67 and 67 and areadapted to be held in their adjusted positions by clamping bolts 69-shown more clearly in Figures 14 and 15. i

That is, the extensions 67- and 67' are provided with lengthwise slots70 of T-shaped cross section for receiving complementary heads ofthebolts 69 which in turn are engaged in apertures in the outer i wallsof the brackets 68 and .-68- respectively, Figures 5,1 i and 15, topermit lengthwise adjustment of the brackets along their respectiveguides 67 with the plates -50.

The inner portions of these brackets 68- and 68 are operativelyconnected to their respective slides -50 and -50' to move therewithlengthwise of the machine when adjusted by means of their respectivescrew shafts 52, Figures 14 and 15.

The brackets 68 and 68' are provided with vertical'guide ribs -71 whichare T-shaped in cross section for engagement in complementary slots 72-in the 1 adjacent portions of the corresponding slides .50' as shown inFigures 5, 14 and 15.

The object of these sliding connections between the brackets --68 and68- and the corresponding slides 50 on the vertically movable sideplates 29 is to permit vertical adjustment'of those plates by theirrespective screw shafts l4 and 4l, Figure 25, as previously described,it being understood that the brackets 68 and 68' are held againstvertical movement by reason of their connections with the stationaryguide members .67 and 67 while at the same time they may be movedlengthwise of the machine along the slots l9- and 70 when adjusting theslides 50 through the medium of their respective screw shafts -52.

I An approximately equal number of inverted labels as 0 Figures 7 8 and10 are stackedflatwise one upon the other upon the several platforms ortables -42 with their ends closely adjacent the rear and front abutments55- and 55 which, together with the platforms 42-, have been previ-,ously adjusted to correspond to the lengths of the labels, it beingunderstood that the label support with the labels thereon will also beadjusted vertically to bring the uppermost label into contact with theunderside of the rolls on the mandrels as the latter are fedhorizontally along the guide bars 6 and that the side plates '-29 willalso have been previously adjusted vertically to conform to theparticular diameter of the rolls to be labeled.

Label pasting mechanism Suitable means is provided for automati eallyapplying paste to the upper surfaces of the front and rear ends of theuppermost labels of the several stacks so that as each mandrel with theunlabeled rolls thereon is rolled from its starting position along theupper surfaces of the labels the rolls will adhesively pick up thepasted front ends of the labels and wrap the latter around theperipheries thereof until the rear pasted ends of the labels are broughtinto overlapping relation with and adhesively secured to the outersurfaces of the previously pasted front ends, it being understoodthatthe lengths of the labels will be somewhat greater than thecircumference of the rolls to permit said r overlapping relation.

The first paste-applying means comprises a horizontal paste-containingtrough -T- mounted upon and between the side plates to extend entirelyacross the front ends of the label holders -42 for longitudinaladjustment with said plates and also for vertical adjustment with thesupplemental frame sections -29 asshown in Figures 1, 2, 5 and 7. p

A pair of parallel rocker-shafts. 73

and 7 l are ournaled in suitable bearings in the side plates 50 andintermediate bracket -66- to extend the entire length of the trough T-near the upper rear edge thereof as shown in Figures 1, 2, 5and 7,

the shaft 73 being provided with a plurality of crank-arms 73' carryingat their outer ends a rod, or wire 73", which is movable witlithe shafts73 1nto and out of the paste in the container T for transferring thepaste to a plurality of wipers on the shaft 74 for re-transfer to thefront ends of thelabels in a manner presently described. See Figures 2,5 and 7.

The shaft 7% is arranged in a plane above and at the rear of the shaft73 and is provided with a series of crank arms 74 carrying at theirouter ends a corresponding number of wipers -74:-, one for each stack oflabels '0-,having.convex'o-uter'faces-normally lying in the path ofmovement of'the wire 73 to permit the paste to be spread thereon by thewire as the latter is moved across the same, said wipers being arrangedto apply the paste thereon to the central portions of the upper faces ofthe front ends of their respective labels immediately following theapplication of the paste thereto by the wire 73. See Figures 2, 5 and 7.

The shaft -'Z3 is normally in position to hold the wire i73- in thepaste in the container T-- and is adapted to be rocked from its normalposition at each movement of the conveyor with a loaded mandrel thereonand for this purpose a cam lever -75 is pivoted at -75 to the bracket-68 toextend rearwardly from its pivot with its cam 75'- in the path ofthe conveyor blocks 15- so that the rearward movement of each block withthe loaded mandrel therein will engage and depress the cam lever 75. SeeFigures 2, 3 and 5.

The rear end of the cam lever 75 is connected by a link 76 to a crankarm -76 of a stub shaft 77 which is journaled in the bracket -68 and isprovided with a forwardly projecting crank-arm thereon after which thewire and its operating means including the cam lever 75- will bereturned to their normal positions by a retracting spring -81-, shown inFigures 2 and 16.

Immediately following the return of the wire -Z3 to its normal position,after applying its paste to the wipers -74-, the shaft 4 carrying thepreviously pasted wipers 74 will be rocked from its normal position tocause said wipe-rs toapply I the paste to the uppermost label and forthis purpose a relatively short rock-shaft -82 is journaled on theright-hand side-plate 68 near the front end of the machine and isprovided on its outer end with a camcrank 83- having its cam-face 83-normally disposed in the path of the corresponding bearing blocks 15 tobe depressed thereby as the loaded mandrel therein is moved rearwardlyfrom its starting position. See Figures 1, 4, 5 and 18.

The inner end of the stub-shaft 82- is provided with a crank-arm '82connected by a link 82 to a toothed segment 84lwhich is pivoted at S4 tothe ad-v upon which the hubs of the wiper-arms .74 are journaled forlimited relative angular movement. See Figures 1, 2, 5, 7 and 9.

The gears 85" are held against axial movement by collars -86 which aresecured by set screws or other fastening means to the shaft '-74iwhilethe hubs of the sev eral wiper arms 74 are held against axial movementbetween their respective gears -85- and collars 86 which are secured byset screws or other fastening means to the hubs 85- of their respectivegears for angular movement with said gears. See Figures 9 and 11.

Each collar 86 is provided with an end lug '-87 projecting into acircumferentially elongated slot 87- in the hub of the adjacent wiperarm 7J- for engaging one end of a coil spring 87 which forms a yieldingconnection between the wiper arm and collar 86 and enables the wipers 74to engage the labels with a yielding pressure to compensate for slightvariations in the height of the labels as shown more clearly in FiguresSand 11 and also causes a slight sliding movement of the wipers upontheir respective labels to irregular spreading of the paste when therolls are brought into contact therewith.

It is now clear that the entire series of wipers -7 lare rocked fromtheir paste-receiving positions to their paste-applying positions andreturn at each depression and return of the cam 83 and independently ofthe shaft 74. thus completing the initial pasting operation.

Label-gripping hubs 88- (one pair for each stack of labels) securedthereto by set-screws 88 or equivalent fastening means to rocktherewith, each hub being provided with a tangentially extending gripperarm 89 pivoted thereto at 89' for vertical rocking movement andyieldingly urged forwardly and downwardly by a spring -89" as shown moreclearly in Figures 9 and 10 to engage the uppermost label with ayielding pressure and thereby to compensate for slight variations in theheight of the corresponding stack of labels.

The label-engaging faces of the grippers -89- are preferably serrated toreduce the liability of slippage thereof on the labels.

Suitable means is provided for automatically operating the rock-shaft 7l and grippers 89 thereon relatively to the loose gears -85 and for thispurpose a cam lever 90- is secured to a pivoted stud 90 on the carriage68 at the left hand side of the machine just at the rear of the camlever 75 as shown in Figures 1, 2, 3 5 and 17 the pivotal stud 90 beingprovided with a crank-arm 90"- which, in turn is connected by a link 90to a toothed segment 91, the latter being pivoted. at -91 and meshingwith a tight gear -91" on the shaft 74: as shown more clearly in Figure17.

The cam lever -90- is yieldingly held in its up position in the path ofmovement of the mandrel-supporting bearings 15' by a spring -91-, Figure3, thereby normally holding the grippers 89 in engagement with thelabels, said cam lever being adapted to be depressed to withdraw thegripping members from the labels at about the same time that the wipers-74 are withdrawn from their paste-applying positions to al low therolls a on the mandrel to have free contact with the previously pastedportions of the labels without interference with the wipers or grippers.7

As soon as the uppermost labels have been adhesively picked up by therolls and while the latter are rolling the labels thereon, the shaft 74and grippers -89 are returned to their gripping positons by theretracting spring 91- for the cam lever -90 thus completing the initiallabel-pasting and gripping operations. I

It will be noted, however, that each wiper 74- is located between eachpair of grippers -89 so as to make a single initial application of thepaste to each label substantially midway between the grippers andopposite longitudinal edges of the labels.

Bear and pasting A cam-lever 92 is pivoted at 92' to the right hand side6 of the frame to projectinto the path of the corresponding mandrelbearings 15 some distance to the rear of the cam lever 83 (Figures 4 and5) to be depressed thereby as the loaded man drel is moved rearwardly,said cam-lever '92 being connected by a link'92 to a crank arm 92 on theadjacent end of a rock-shaft 93 which is journaled in the rear ends ofthe opposite lengthwise members 29 to rock about its axis as the camlever -92 is depressed. SeeFigures 2, 4, 5 and 7.

This rock-shaft 93- extends along the upper rear edge of a pastecontaining receptacle T and is provided with crankarms -9=. carrying awire 93" which.

is movable into and out of the paste in said receptacle for transferringthe paste to a series of Wipers by which'the paste is applied to therear ends the uppermost labels in a maner presently described, saidcam-lever 9 parts actuated thereby being returned to their normalpositon by a-spring -93, Figure 2.

The paste containing receptacle. T is secured to and between themembers29 just at the rear of the label holder as shown in Figures 2, 4, 5 and7 A cam-lever 94- (Figures 2, 3 and 5) is pivoted-at 9l' to the lefthand side of the frame l to project into the path of themandrel-bearings 15 some distance to the rear of the cam-lever and iscon nected by a link 94l to a toothed segment 95- which is pivoted at95- to the'adjacent frame member -1- and meshes with a tight gear 95 onarock-shaft 96 for rocking said shaft in one direction against theaction of a retracting spring,

95- shown in Figure 3. i

The rock-shaft 96 is journaledin the opposite side members.-29 and ispro vided with a series of pairs of crank-arms 9", one pair for eachstack of labels c, and each crank-arm is. provided with a convex wiper96 in the path of the rod or wire 9 3 to receive paste. therefrom asthewire is rockedupwardly and rearwardly from its normal position by therock shaft 9 in the manner'previously explainerhsaid wipers beingarranged-to apply the paste thereon to. the upper surfaces of the rearends of theuppermost labels at opposite sides of the longitudinalcenters thereof as theshaft 96 is rocked by the depression of the camlever 9lasshown by dotted lines in Figure 8. r

Each crank-arm ,96 is preferably composed of sections, one of whichisadjustably secured to the rock-shaft 96' while the other sectioncarrying the wiper -96"' is yieldingly connected to the first namedsection by a spring 96- as shown in Figures 8 and 12 to cause thewipersto: engage the labels with a sliding contact for spreading thepaste in thinlayers thereon.

7 Rear grippers Suitable means is provided for holding the rear ends ofthe uppermost labels'against displacement while the labels are beingwrapped upon the. rollsby the rolling motion of the rolls a thereon andwhile the paste is being applied thereto, and also for releasing thelabels after the wrapping, and pasting operations are completed-and forthis purpose arock-shaft 97 is journaledin the opposite side members-29' and provided with a series of hubs 97 having gripper arms 97.similar to the front hubs 88 and gripper arms -89' except that there isonly one hubv 9Z and one gripper arm 9'Z for each stack of labelsandthat each hub and gripper arnris arranged midway between thecorresponding, pair ofwiper arms 96 to engage the corregppnding centralportion of the uppermost la e V That is, each hub 97 is secured to -theshaft 97 while each gripper-arm 97" is pivot-ally and yieldingly mountedon its corresponding hub in substantially the same manner as the frontend grippers shown in Figure 10.- i p V A. cam-lever 98- is pivoted at98 tor the right hand side member 67 (Figures land 5) near the rear endof the machine to project upwardly into the path of the mandrelbearingsl5 to be engaged and depressed thereby as the loaded. mandrelcontinuesits rearward movement,said camlever beingiconnected by a link,-98 to a.toothed segment 99 which, in: turn, is pivoted at 99- tothe side member-67 and meshes with a tight. gear 99" on the gripper shaft 97 forrocking said shaft an d,v grippers 97- thereon upwardly and rearwardlyfor releasingthe labels just pre ceding the completion of the wrappingoperation and pasting of the rear endof the-labels over and upon thepreviously pasted front ends of the samezlabels to the rolls aspreviously explained, thus completing one labeling operation.

, Are-soon. as the cam-lever 98 isreleased by'the passing ofitsoperating member -15- it, together with the segment 99. and partsactuated thereby, is vreturned-to lts normal grippingposition.by-aretracting spring Label table feed I Suitable means isprovided for automatically intermittingly feeding the label-supportingcarriage upwardly a distance-equal to the thickness of a labelimmediately following the removal of the uppermost labels causedby thewrapping-of saidlabels around and upon theirrespective rolls aand forthis purposea lever100 is securedHto-a rock-shaft100 at the rear end ofthe frame 1 and projects upwardly therefrom into the path of mandrelbearings 15 to be thereby rocked rearwardly and downwardly as the loadedmandrel continues its rearwardmovement. See FiguresQ, 3,5 and 6. a

The rock-shaft- 1 -100 is provided a crank-arm 100 connected, by a linkfor engaging the teeth of a ratchet wheel of the motor.

l02 tight on the shaft -4'? to rotate said shaft and thereby causeslight angular movement of the upright screw shafts 44 and corespondingupward 3 movement of the label-supporting carriage 4O at each rearwardmovement of the rock-arm 100, the operating mechanism for the carriagebeing arranged to raise the carriage upwardly a distance equal to the Ithickness of the label at each cycle.

The continued rearward movement of the loaded mandrelwith the labeledrolls thereon causes the conveyor block -l5 to release the cam lever-100- and allowed the latter, together with the parts operated thereby,to be returned to its normal position by means of a spring 103- shown inFigure 3.

At about the same time that the lever -100- is rocked rearwardly'by therearward movement of the upper side of'the conveyor block 15- theopposite conveyor block 15 will engage and operate the switch member26., Figure 21, to open the switch 8 and thereby stop the motor M andconveyor 11 driven thereby, thus leaving the mandrel with the labeledrolls thereon directly over and upon .the delivery table 5 until theswitch -8 is again closed byhand to start another cycle of operationWVhile the loaded mandrel with the labeled rolls thereon is resting uponthe table 5- the mandrel may be removed from its bear ing 15' and '-15'and withdrawn endwise from the labeled rolls leaving the latter to bedisplaced rearwardly from the table for drying the pastethereon untildisplaced by the next succeeding series of labeled rolls.

' When the mandrel is removed from the labeled rolls it is taken to thepaper-roll cutting machine to be reused'for receiving another s-et ofrolls to be labeled, it being understood that the presentmachine will beinstalled in close proximity to said cutting machine for convenience oftransfer of the mandrels from one machine to the other.

Operation When the machineis at rest one set of conveyor blocks will bedisposed at the front end of the machine and another set at the rear endof the macaine, at which time both of the. motor-controlling switches s.and -s will be opened.

One oft-he mandrels with a series of rolls to be labeled thereon is thenplaced by hand in the conveyor blocks in'the front of the machine afterwhich the switch swill be closed by hand, thereby starting the motor andconveyor belt driven thereby until the conveyor block 15- at therear ofthe machine is moved out of engagement with the switch member 26 therebyallowing the switch s to close, the switch -s being then released to itsopen position with the assurance that the motor M and conveyor belt'willcontinue to operate to cause the rolls on the loaded mandrel to rollalong and upon the uppermost labels whichhave been previously pasted attheir front ends in the manner described so that immediately upon thefirst contact of the rolls with the front ends of the labels the latterwill be picked up by .the paste thereon and wrapped upon the rolls asthey continue thelr rearward rolling movement. p

When the rolls with the labels wrapped thereon approach the rear end ofthe ma chine the rear ends of the labels will be pasted in a mannerdescribed and adhesively applied to the outer faces of the previouslypasted ends of the labels, thus completing the labeling operation of therolls on that particular mandrel.

Immediately following this labeling operation the rear conveyor blockscarrying the labeled rolls will operate the switch member 26- to openthe switch and thereby stop the motor with the rolls resting upon therear delivery table 5 and at the same time presenting the nearestsucceeding set of conveyor blocks to the front end of the machine forreceiving another loaded mandrel.

As previously stated, with the rolls are labeled in the manner describedand disposed on the table 5 the mandrel is removed and returned to thepaper-cutting machine for re-loading leaving the labeled rolls on thetable to be displaced by the nearest succeeding set of labeled rolls.

The labeling machine shown and described simultaneously andautomatically labels a relatively large number of rolls in one and thesame operation, thereby greatly reducing the labor and also greatlyincreasing the output for a given period of time, but it is evident thatvarious changes may be made in the detail construction and operation ofthe machine without departing from the spirit of this invention.

What I claim is:

1.1m a machine for applying labels to toilet paper rolls, means forsupporting a multiplicity of stacks of labels side by side inparallelism with their uppermost labels in substantially the same plane,means for applying paste to both ends of the upper surfaces of theuppermost labels while the latter are lying fiatwise in the stack, meansfor rotatively supporting a'corresponding number of toilet paper rollsend to end in alignment withtheir respective stacks of labels, and meansfor moving the roll-supporting means along the upper sides of saidstacks with the rolls in contact with the pasted surfaces of
